| Do you know each other? http://livejasmin.in.net/ jasmine live In this case, the researchers used a liquid crystal similar to the materials used in LCD television and computer displays that could operate in a simple setup, does not require external voltages or magnetic fields and works at room temperature. The scientists then added a chemical component that twisted the liquid crystal molecules into a helical shape and then added dye molecules that rested in the helical structures. The dye molecules change their shape when irradiated with light, thus altering the optical properties of the material. |
